“Breaking Dawn” is the fourth and final book in Stephanie Meyer’s beloved Twilight series. Because the scope of the book is so expansive, filmmakers decided to tell the story in two movies à la Harry Potter.

The movie's tagline -- "Forever is just the beginning" -- speaks volumes about the story.

Picking up where "Eclipse" left off, the movie starts with Bella and Edward’s wedding and then goes on to Bella’s unexpected – and extremely perilous – pregnancy.
